The phrase "the month of Abib" in these three situations is properly connected with the Exodus and not Passover. So why in Deuteronomy 16 is "being brought forth out of Egypt" used in connection with Passover and not Unleavened Bread as in all the other scriptures?
Exodus 23:14-17, Exodus 34:18-24, and Deuteronomy 16:1-17 all have something in common. They all pertain to the three festival seasons: Unleavened Bread, Pentecost (called the Feast of Firstfruits), and the Feast of Tabernacles. In neither one of these contexts is either Passover or the Last Great Day mentioned at all. What we have in these three chapters are specific instructions for these three Feasts. This is especially important to Deuteronomy 16. Deuteronomy 16 is not about Passover. It is about the Feast of Unleavened Bread, Pentecost, and the Feast of Tabernacles.
